FIRE-BOX LlNlNG FOR STOVES, FURNACES, 86C.

SPECIFICATION forming part of Letters Patent No. 371,165, dated October 11, 1887.

Application filed October 10, 1885.

Serial No. 179.565. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES TALBOT BARNES, a citizen of the United States of America, residing at Chicago. in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fire-Box Linings for Stoves, Furnaces, &c., of which the following is adescription, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain novel improvements in fire-box linings, which will be' fully understood from the following descrip tion when taken in connection with the annexed drawings. in which- Figure 1 is a front view of a pair of my improved liningsections in the position of being connected together or disconnected. Fig. 2 is asirnilar View of the parts connected. Figs. 3 and 4 are horizontal sectional views. Fig. 5 is a detail view. Fig. 6 is a plan View in detail. Fig. 7 is a detail elevation, partly in section. Figs. 8 and 10 are edge views, and Fig. 9 is a perspective view, of one of the sections.

In the annexed drawings, A A indicate the liningsections, which are adapted for fiatsided fire-boxes or for circular fireboxes, and which have the general forrn,in horizontal section and top view, shown by Figs. 3 and 4, presenting the curves d d and notched wings I) I). These sections are connected together by a joint, as shown, consisting of the wings b, having a vertical flaring slot, t, in the eye of which is loosely applied a rounded head, B, which is formed on a doublebeveled extension, f, free to move laterally in said wing.

It will be observed that on opposite sides of the eye or wing b, when thelining-sections are in contact with the wall E of a fire-box,spaces c are left, which serve as airllues; also, that the sections are vertically grooved or notched at e for the purpose of leaving fragile portions for conveniently breaking oft portions of the sections in fitting them to a fire-box. The sections A A are also constructed, each with a lower extension or skirting, a, whichis preferably curved inwardly, as shown, and grooved as at 10, both vertically and horizontally, for the purpose of allowing portions of the skirting to be broken away. between the ridges when a front grate is desired. The upper end of each section A is also provided with a horizontal flange, D, which extends outward, as shown. Part of this flange extends beyond the end of the said section, so that when two sections are jointed together said part overlaps the head B and neckf and covers the up' per end of thejoint, as shown in the top view, Fig. 6.

It will be observed that I connect the sections together by simple hinge-joints, which will effectually prevent endwise movement or slips horizontally without the use of supernumerary locking devices.

It will also be seen that when the sections are together the upper ends of the joints are covered by the lips or extensions n, which exclude ashes and cinders therefronnand, finally, it will be seen that I combine with each sec tion A an integral portion thereof, which affords a downwardly-converging skirting.

I am aware that it is not broadly new to connect the sections of a lining by means of interlocking portions, by shoulders, and male and female portions; nor is it broadly new to construct the sections of a lining with grooves, affording portions which can be broken off in fitting the sections into a fire-box. I do not, therefore, claim such devices.

\Vhat I claim is- 1. A fire-box lining composed of sections detachable from each other and connected by hinge-joints, as described, in combination with the covering portionsn for said joints formed on the sections, and the top flanges, D, grooved as described.

2. The lining-sections A A, connected by hinge joints and having depressions 0. adapted to form air-ducts, as described, in combination with the grooved skirting, the grooved top flanges, and the grooved portion adapted to coversaid joints, substantially as described.

3. The lining-sections A A, hinged together and provided with covering port-ions for the upper ends of the hinges, in combination with grooved wings I) b, a grooved skirting, a, and a grooved flange, D, substantially as described.

CHARLES TALBOT BARNES.
